An extensive polio vaccination campaign started on February 26 in 21 of Afghanistan's 34 provinces, the country's Health Ministry said. The Taliban-controlled ministry's spokesman, Sharaf Zaman, said the four-day-long campaign aims to inoculate 7.6 million children under the age of five. Zaman asked local religious leaders to cooperate with the inoculation teams.

Pakistan and Afghanistan are the only countries in the world where polio has not been completely eradicated. To read the original story by RFE/RL's Radio Azadi, click here.
